`
`Transport and installation of the Machine
`
`Selecting the Location for Installation
`
`To guarantee a safe and precise work of the machine the location of your press
`should meet the following conditions:
`
`Floor allowing only slight vibrations
`Vibrations caused by other machines should be kept away of the press.
`
`Normal humidity and temperature
`
`Good accessibility of the machine from all sides. Sufficient freedom of
`motion for operator and maintenance engineer - the space for opened
`windows. doors and flaps has to be taken into consideration.
`
`Sufficient space for additional appliances as
`
`-
`
`tablet cleaner Type QUADROMAT and
`
`- PHARMAPRESS MEBWERT ANALYSE (PMA)
`
`The location for installation should be as free of dust as possible.
`
`Transport of the Machine
`
`The machine's packaging is determined by the route it takes and the distance to
`its destination. We recommend that you have a professional haulage company
`ship the machine to its final destination.
`
`in no case may the machine be transported with rollers.
`Regardless of whether the machine is packaged or not, it can
`easily tip over and injure anyone who may be standing nearby.
`
`The machine has a threaded hole in the head part for screwing in the supplied
`lifting screw when the machine is moved after being unpacked. The machine can
`be attached to this lifting screw.

`
`Unpacking of the Machine
`
`@=
`
`Please compare all accessories and spare parts with the delivery note
`immediately after unpacking. Claims at a later date cannot be taken into
`consideration.
`
`The following is a description how to unpack the machine. It can happen that one
`ore more points does not apply so that you can skip them because the kind of
`packing depends on the way of shipment.
`
`Unpacking of the machine:
`
`Remove top cover of the packing.
`
`Remove the side walls.
`
`Remove the plastic foil towards the top. A seaworthy packed machine is
`completely wrapped up with plastic foil so that the foil has to be cut open at
`the lower edge first.
`
`Depending on the kind of shipment you will find two to four fastening bolts in
`the corners of the base. Unscrew them.
`
`One lifting screw is delivered (see List ofAccessories). Screw it into the
`tapped hole at the upper surface of the machine headside.
`
`Hang on the machine to the lifting screw and lift it from the crate bottom.
`
`Installation of the Machine
`
`Take care of a suitable base if the machine version is without a wooden socket. If
`
`the machine should be placed on a table the weight-bearing capacity of table
`should be controled because the machine weight is approx 130 Kg.
`
`For execution with wooden socket the stand must be smouth to avoid that the
`machine wobbles.

`
`Cleaning at the Installation
`
`The machine, before its transportation is being sprayed with an anti-moisture
`spray (see EG- Safety Data Sheet of company WD 40 Company Limited for anti-
`moisture WD-40 bulk ware). Hence the machine needs to be thoroughly cleaned
`before its taken into operation.
`
`When cleaning part coated with lacquer avoid using cleaners that might
`seep in and destroy the laquer.
`
`To clean the machine do not use compressed air or high pressure
`sprayers.
`
`The best cleaner would be alcohol or something similar. Avoid using fluffy mops
`and rags for cleaning. In order to clean synthetic material it is best to use anti
`static rags as a final rubb off. Take care that the cleaning solvent does not leave
`any residues.
`
`Regular Cleaning
`
`The machine should be cleaned thoroughly in regular intervals, if possible daily,
`but in any case when changing batch an product.
`
`it is absolutely in your responsibility to adopt the appropriate
`safety measures necessary for the cleaning personnel. Only
`you are aware of the risks and dangers that can be coused by
`the processing material.

`Electrical Connection of the Machine
`
`The machine is connected via a three meters long cable with CEEKON plug.
`
`It is not allowed to use an adaptor from CEE to shockproof
`socket even if only one phase of the CEEKON plug is
`connected because there is the danger of reversed
`connections.
`
`The entire connection can be read from the circuit diagramm and the typeplate of

`
`Preparation for Startup
`
`To make shure that the machine is ready for operation please adhere to the
`following order.
`
`Make sure that access to the machine, especially to the EMERGENCY STOP
`switches, is not impeded.
`
`Before starting operations clean the machine thoroughly and lubricate well.
`
`It should
`Care should be taken to see that the V-belt is not fitted too tight.
`furthermore be seen that the swivel flange on which the motor is mounted can be
`tightended so that the weight of the motor lst not carried by the V-belts alone.
`
`Before switching on the motor, it es imperative to press a few tablets by
`hand, this is the best method of finding out whether all adjustments have
`been carefully made.
`
`Lubrication
`
`The machine is completely greased in our works and is tested in all speed ranges
`for several hours.
`
`For further lubrication please adhere to the special advices.
`
`All oils and greases recommended have got the USDA H1 authorization by
`the US Food and Drug Administration.
`We recommend every customer to use the lubricants by the Kliiber
`Lubrication company as they have got special lubrication qualitys. These
`lubricants should definetly be used in the food and pharmaceutical
`industrie.

`
`The following points should be daily with a multi purpose grease:
`
`The nipples of the main shaft,
`
`The nipple of the press eccenter,
`
`Nipples of the intermediary shaft,
`
`Nippel of lower piston,
`
`The bearing point of the hopper action lever.
`
`<9‘ We recommend Klfibersynth UH1 14-151 by the Kliiber Lubrication
`company.
`
`The grease has to be filled into the grease press as tight as possible and without
`holes. Test the grease press before using because holes in the grease can hinder
`its function.
`
`The following parts should be oiled or greased daily:
`
`The two rollers ofthe hopper action lever and the lifting rod running on the
`cams of the main wheel. The cams the rollers should also be slightly oiled or
`greased.
`
`The bearing point of the hopper action lever.
`
`The bearing points of the lifting rod.
`
`The guide rod.
`
`The upper piston.
`
`A few drops of oil should also be given to the two rollers at the hopper as
`well as the ball pin located inside the cap.
`
`is We recommend Klfiberoil 4 UH 1 - 100 by the Kliiber Lubrication
`company.
`
`The hopper can be removed from the die plate when the connection rod has been
`withdrawn.

`
`Should there still be material inside the hopper, lift the latter slightly and place the
`small tin plate, supplied with the machine, underneath it or place the plate on to
`the die plate and draw the hopper over it. Plate and hopper are then removed
`together which effectively prevents spilling of the material. If operations are to be
`carried on with a different kind of material for pressing then the machine should
`first be thoroughly cleaned including the dies and the hopper. When the hopper is
`installed, it is imperative to replace also the connection rod and to secure it. The
`pressure of the hopper can be adjusted by exchanging the pressure springs.
`
`Lapping of Wool of the Punches
`
`The lower punches for such tablets which are difficult to eject should receive a
`lapping of wool which is dipped in paraffin oil.
`
`Depending on the quality of the material to be pressed either only the upper
`inserted part of the punch neck is to be lapped with wool or the woolen thread is
`continued so that also the lower part of the punch neck is covered as far as
`thorough-turned inserted part. lfthe wool lapping is carried all the way thorough,
`some cotton wool can be placed inside the lower punch holder which is also
`drenched in paraffin oil and which thus insures lubrication of the die holes for a
`slightly longer period. These wool lappings should be renewed at least once a day
`if possible.
`
`The lapping should be tight enough and the thickness of the thread be such that
`the lower punch can be inserted without undue pressure into the die holes after
`lapping. Care should also be taken to see that no wool is cut off when the punch
`is inserted into the die hole.
`
`If a lubrication ofthe die is not required, the wool lapping can still be
`recommended because this will effectively prevent material falling past the lower
`punches on to the lower piston.

`Machine Construction and Adjustment
`
`Switch and Button
`
`Depending on the equipment of the machine, there are the following buttons and
`switches at the machine, the switch cabinet and the machine base:
`
`EMERGENCY STOP switch
`
`The machine is equipped with a EMERGENCY STOP switch
`(red button over yellow ground). The machine can be
`switched off with this EMERGENCY STOP switch in
`
`emergency situations. To activate the switch bang it on the
`red coloured head. The machine will be stopped immediately
`and the lamp of the button QUIT (see there) will illuminate.
`
`To take the machine into operation again the EMERGENCY
`STOP switch must be released: Therefore turn the red button
`in the direction of the arrow.
`
`MOTOR ON
`
`E With the help of the illuminating button MOTOR ON the drive
`
`motor of the Press Machine is set in operation. Since the
`Press Machine is not provided with a clutch it is immediately
`set in motion with the speed as adjusted in the potentiometer
`under MOTOR SPEED (see SPEED MOTOR).
`
`The illuminating button is always on as long as the motor is
`on. In case this button is not on then the defect must be
`
`rectifed by an electrician.
`
`0'
`
`Before switching on of the Machine make sure that the upper piston is at the
`upper dead point or at least close to it. Should the upper piston be too close
`to the lower dead point this could eventually lead to the jamming of the
`Machine. This is must specially in case of upper compression range
`between 20 and 30 kN.

`area or the lower doors in the front and in the back are
`
`removed respectively opened.
`
`after you have stopped the machine via EMERGENCY
`STOP switch.
`
`Faulty contitions of the frequency controler are also shown by
`illumination of the lamp. The fault messages can be read from
`the display in the control cabinet. In the operating instructions to
`the frequency controler you will find a description of the fault
`messages.
`
`The machine can not be started as long as QUIT is illuminated.
`

`
`Care should be taken to see that no greater filling depth is adjusted as is
`permissible for the height of the die used because this will force the lower
`punches out of the die guides. Following an alteration ofthe filling depth it
`frequently becomes necessary to also alter the pressure setting accordingly.
`
`Pressure Adjustment (Hardness of the Tablets)
`
`The desired hardness of the tablets (pellets) is obtained by adjustment of the
`worm towards plus or minus (+ or -)_ The clamping screw must be loosened
`before and retightened after an adjustment of the worm.
`
`The ball pin which connects the machine eccentric (consisting of eccenter yoke
`and eccenter block) with the upper piston is screwed in respectively out by
`adjustment and therefore the insertion depth of the upper punch into the die is
`increased respectively decreades.
`
`Height of Punches when Ejecting Pressed Parts
`
`The lower punches should come into line with the upper surface of the dies when
`ejecting the tablets or they should stop some hundredths of millimeters below the
`surface in orderto prevent the hopper from touching the edges of the lower
`punches when pushing the finished tablets away.
`
`By raising the upper round nut (first loosen clamp screw) the lower piston with the
`punches is lifted less, and by lowering (left hand turning) the lower punches with
`the lower piston is raised. If the lower punch is fitted with a stop, the action of the
`latter against the die should only be very slight so that no resistance is felt when
`the flywheel is turned by hand.

`
`Changing the Punches
`
`First remove the hopper from the die plate. In order to accomplish this draw out
`the connecting rod after having first loosened the locking screw. When putting the
`hopper aside, be careful not to damage the underside (running surface) since
`indentations in the surface may cause the hopper to spill some of its contents.
`After loosening the pressure screw the upper punch is removed. Subsequently lift
`out the die plate after first unscrewing the three hexagonal bolts located at the
`underside of the die. Finally the lower punches are removed by loosening the
`retaining screw. Installation of the tools is done in reverse order.
`
`First the lower punches are mounted but not fixed, then the die and the die plate
`are installed and fixed in positon with the aid of the three bolts located at the
`underside, which should not be drawn tight as yet, however, and finally the upper
`punch is attached and its retaining bolt is drawn tight. By carefully turning the
`flywheel by hand the upper punch is moved downward and the loosely fitted die
`plate is now brought into line so that the upper punches can be smoothly inserted
`into the die holes. Leave the upper punches in their position inside the die plate
`and the plate is now drawn tight by fastening the bolts. The retaining bolt of the
`lower punch is now drawn tight in a similar manner. The bolts of the die plate
`should not be driven down by force because this might cause the die plate to
`warp which in turn may cause the hopper to spill its contents. Subsequently the
`hopper should be attached which should be secured in its postion immediately
`with the aid of the connecting rod and locked with the knurled screw.

`
`Startup of the Machine
`
`General Remarks
`
`When all adjustments are carried out in a proper manner no resistance should be
`felt when the handwheel is turned, i.e. as long as the press is turned while empty.
`If, on the other hand, the machine is filled with material for pressing a resistance
`should only be felt during the actual pressing process and a slight resistance
`when the finished tablet is ejected. If the ejection pressure is excessively high,
`the reason may be that the material for pressing is not sufficiently prepared (too
`dull); furthermore the die holes should be checked for any indentation at the point
`of pressure. Such indentations on the dies should be found only after a
`considerable period of service. Such dies are used up and should be replaced.
`
`When adjusting the pressure note that the working point should be such that it
`can be overcome when turning the machine through by hand. If the machine
`cannot be turned through by hand the pressure is adjusted too high, even should
`the hardness of the resulting tablet prove to be insufficient. The poor quality of
`the tablet is,
`in such cases, the result of the poor binding properties of the
`pressing material.
`
`The machine should be cleanded daily, especially should pressing material be
`removed which may have dropped past the lower punches on to the lower piston
`and ejector rod.
`
`The machine should never be turned backwards since this would cause
`
`double dosing. Before starting to switch on the motor turn the machine by
`hand to such a postion that the piston and the punch does not startthe
`operation by pressing, it is rather advisable to overcome the working point
`by a hand turn and then to start the motor.
`
`Pressure Adjustment
`
`The ball pin should not be screwed out to far by turning to the left, because
`othenivhise there is the danger that the upper punch touches the feeder.
`Therefore please proof by turning the handwheel that the upper punch does not
`touch the feeder after an adjustment.

`
`Loosening a Machine which has jammed under pressure
`
`It may happen that, due to a pressing compound which fills unevenly or through
`the setting of excess pressure, the machine mayjam - that is, not master the
`highest pressure point. The machine is so sturdily constructed that no harm will
`come to it, but the drive motor can be damaged if it is not switched off
`immediately. Therefore, it is advisable to incorporate a motor safety switch in the
`power supply line.
`
`If the machine does happen tojam under pressure, it can only be
`released by turning the drive flywheel forcibly and suddenly
`backwards.For this purpose the belt guard is removed and the flywheel is
`turned sharply backwards - if possible by two people. In this contingent it
`is always impotant for the filling shoe to be removed from the machine
`first. Any attempt to loosen a jammed machine by forcible readjustment of
`the pressure or of the filling depth regultation would be both useless and
`harmful.

`
`Special Designs
`
`The measurement ofthe ejection-, upper punch- and lower punch compression
`force and the displacement measurement are special designs and does not form
`part of the machine as normally supplied.
`
`Force-Measurement with DMS
`
`Where a machine is equipped with strain-gauge strips in the upper piston and in
`the lower piston the following accurate measurements can be carried out:
`
`Measurement of the compression force of the upper punch.
`
`Measurement of the holding-up force of the lower punch.
`
`Measurement of the ejection force
`
`a) without step-up gearing 1:1
`
`b) with step-up gearing infinitely variable setting of the enlargement on the
`instrument from 1 to 10.
`
`4. Measurement of the friction force within the hollow die. This force results
`
`from the difference between compression force and holding-up force.
`
`@=
`
`You will find the measured data in the calibration diagram.
